To all whom it ma concern? p lie it known tint l. Lizwm E. Wausau. a eitinen ol' the l'iiiteil States. reuidiniz at Kellogg. in the ouiity of Shoshone and State of ldiilio. have invented new mul use ful lmproveiiienta in llevoluhle Sizing'- Hereenii, of wliieli the following in a peeilieatioii. a

My invention relatel to iin apparatus wliieli is eapeeiall)- designed for tlie sereening aiid grading or sizing of ores.

lt consists of one 'or more seta of down wiirdly convergent revoliilile i-u-i'eeus to ieeeive the material. iiiid iii ii eoiiihiniitiou of iartii iind details of eoustrnet ion. wliieli will ie more fully explained by refereuee to the iieeouipiiuyiiigz drawings. in wliieli Figure l ia ii vert ieiil iwetiouof the rit-reen. Fi in a plan view with housing partly hrii en away; Fitz. tl iii a iteetional view of one of tlie iipider armii.

lt iti the olijeet of my invention tu iroi'ide ii iieieea ap airatiu-i ao eoiii-truetei im to Nine iuid prat e. the iiuiterial delivered ttpoii the sereena. and to im eoiiutriiet tlie oereen au to eaiiae ii unlmtiiiitiiilly eren wear over tlie whole airfare of the aereeii.

'I'lie maeliiue iii dei-ii ned to revolve at ii slow rate of iipeed nui to deliver the lluei' partieleii of ore through tlie nereeii: tlie eoaraei' piirtieles passing over it aud iiito a liitnnler at the bottoni of the spider. 'lho liner piirtielea tliat pasa tliroiuzli tlie laerei-n. drop ititii au inverted eolie-sha ied housing. down the iiielined inner wall o wliieli they iilide to a lannd'er at the bottom of tlie lioasiiuz.

The maeliine naiv he iiiiule of ditl'ereiit iiizea. and of ditlereiit devrees of iueliiiat'ioii `for handling various elaam'ii of ore and pulp.'

It iii designed to size the uuiterial in a eoueentratinn or ore treating: plant. lait may he i l uned to advantage for the sizing: of roelc.

aand or like iiaiteriiil. as iu eouerete tir paveiiieiit work. or the like.

The aei'eelai -l are uuide widest at t ie top. and eonverge doauwardlv toward tlie bottoni of tlie eolie wliieli supports tlielii. l llie iiiiiterial to lieiiized or graded is first reeeived itpeu tlie up ier portion of the screen wliieli. bein,"1 the wit est. allows the material to lie distributed over tlie greatest stirfaee of tlie ei-een.

receiving a type well known in this art and each of the latinders being, in practice, provided with a suitable outlet.

13 is a timber or equivalent frame, and i4 are lu or straps riveted to the housing and a apted to rest'on the frame so as to support the housing, and lceep it in place. There may be aa many of these lu as the requirements of the apparatus mag: necessary for the pro r support.

` 15 is the latini er which carries away the under sized material that has missed through the screen, in case only one. series be used.

1tl are braces fixed to the interior of the housing 1, and extending in such position as to forni snp irts for the launder f2 which mali( be bol to these braces.

he tip r jonrnal-box f8 of the shaft. is support upon a timber or part of the fraaie-work 17 aiid the lower end of the shaft is tiiriiable in a step at 22.

lt) is n bevel- 'ear fixed to thel lower part. of the shaft, an 20is a bevelinioa mounted iipon the shaft 2l, and tirough which power is -transmitted to rotate the apparatas.

It will be manifest that any suitable driving iiiechanisin-inay he. substituted for that here described.

23 is a spray pi ie passing over the screen, and water there roiu delivered upon the ,screen itiid material will loosen any particles of material which may adhere ou the inside, thus allowing it to ritii down and into its launder at l2. 24 is a siinilai s ray pipe extending on the uiuler side of t e screens and between the screen and housing, and the jets from this pipe sei-ve to loosen and force inwardly any particles of material which iiiay stick in the meshes of the screen. rnd which arc not reatlilv removed by the spray from pipe 2.3. hese spray pipes may be adapted tor use water, steam, or air. depcndiii upon the character 46 of the material. and w ietheixthe grading is to be wet or dry.

2T is a sluice or liiunder from which the ninterial is delivered into the aparatos: the flow of the iuaterial being controlled -hy 50 gates or other means not here shown.

ab vertically dis ioset 30 inthe spider, means by which the sci-ecn rallies are removably attached to thespider. means for delivering material to be sc iarated to the interior of the funnel. a launt er to receive the material not passing tlirou rh to'sccure by Letters lit-V tho screen, a second launder to receive t ic f amavo material which has passed through the screen, a irojccting flange upon the lower part of tie spider, whereby tine material owing down the outside of the screen will be discharged outwardly, means for snpplying water to the inside of the screen, anti a aunder into which said line material is delivered.

2. In an apparatus of the character lde scribed, a vertical?v re-voliible shaft, a funnelmhaped spider :ted to said shaft,screens., the frames of which fit the openings in the spider. means by which the screens are attaclied thereto. means for supplying iuaterial upon the inner surfaces o the screens, a launder for the coarser material, a second launder for the material which passes through the screen. a directing flange snrrounding the lower part of the spider to de liverksaid material outwardly. spray pipes extending substantially parallel with the screen upon the inside and outside thereof.

3. ln an apparatus of the characterdcscribed. a funnel-shaped spitler having a central hub and having screen supports on its lower portion, a .vert ically revoluhle shaft. to wiich the hub of said spider is lt'cyed, screens fixed upon the inclined spider and conforming `to the openings therein, an exterior housing. means for supporting it out of contact with the spider. means for delivering material into the upper part. ot' the funnel lo low down over the screenen' a launder located near the bottom of the funnel. sup irts fixed lto the housing and extending lneath' thc launder.

4. ln an apparatus of the character dewrila-d. a funnel-shaped spider. a vertically revoluble shaft to -which the hub of the spider is keyed` downwardly convergent scieens.ixed to register with the openings of the s ider, means for supplying limiterial' to tic iiiterioi' and upper part of the spit-lento llow downwardly over the screens.

and spray pipes parallel with and contigoons to the inner and outer surfaces of the screens. an exterior conical housing suptiiort: ed out of contact with the spider and a apted to receive tiiid direct the material passing through the screens'. a launder contiguous tothe bottoni of the funnel to receive thc coarse material. a second launder into .which the material passing` the screens is delivered. and an annular flange projm-ting below the screens to divert the material which flows down thc outsidt` and direct it into the sccond launder.
